About Crystal Canyon Raid
Crystal Canyon Raid is the hard map, built for players who have already beaten the valley. Purple dusk light falls over a rocky canyon studded with glowing crystals, and the invaders have changed tactics. From the third wave on, many saucers no longer follow the road at all. They fly high and straight across the canyon toward the castle, so cannons, which only hit ground targets, cannot touch them. Ballistas, frost spires and tesla coils are the only answer to the sky raiders, and you will have to decide how much of your gold goes to the air and how much to the armoured tanks still crawling along the winding road. The crystals are your secret weapon. Any plot next to a crystal glows violet and gives the tower built on it thirty percent more damage, so the best defence grows around those glowing spots. You have only fifteen lives, enemies gain health faster from wave to wave, and calling a wave early pays extra coins for brave players. Twenty waves end with a mothership escorted by a cloud of fliers. Survive with every life intact and you are a true canyon commander.
How to play
Flying saucers ignore the road and head straight for the castle; only ballistas, frost spires and tesla coils can hit them. Plots beside crystals glow purple and boost damage by 30%. Tap a plot to build, tap a tower to upgrade or sell. Keys: 1–4 build, U, S, Space, F.
